Abstract

Conventional monitoring method is used for evaluation of the reservoir and levee at the highest height sections. In recent years, automated measurement technology has been developed, and the measurement results are transmitted, collected and stored in real time into management office. Despite the development of real time monitoring technology, the measurement results are not used directly or indirectly with facility management at real time. Recently, as wireless sensor network measurement technology has been developed based on internet of things, this study proposed a real - time measurement and evaluation system based on wireless sensor network technology in the reservoir structure. As a result of the seepage analysis for the application, it was confirmed that the volumetric water content changes together with the change of the seepage line inside the embankment body according to the change of the water level of the embankment. In other words, the applicability of the measurement system with the volumetric water ratio set as the sensor node was verified.

저수지 및 제방에서의 계측은 가장 높이가 높은 구간을 선정하여 계측기를 매설하고 측정하는 집중계측 방식으로 최근에는 자동화 계측기술이 발달되어 실시간으로 계측결과가 관리사무소로 전달 및 수집, 저장되고 있다. 실시간 계측기술이 발달되었음에도 불구하고 계측결과가 시설물 관리와는 직접적으로 이용되지 못하고 있다. 최근 사물인터넷 기반의 무선 센서 네트워크 계측기술이 발달함에 따라 본 연구에서는 저수지 및 제방 구조물에 무선센서 네트워크 기술을 기반의 실시간 계측 및 평가시스템을 제안하였다. 적용성 평가를 위한 침투해석 결과 저수위 변화에 따라 제체 내부의 침윤선 변화와 함께 토체의 체적함수비가 함께 변화하여 체적함수비를 센서 노드로 설정한 계측시스템의 적용성을 확인하였다.
